A most beautiful path navigation method and system based on street view aesthetic scoring

Abstract

The invention relates to a method for navigating the most beautiful paths on the basis of aesthetic scores of street scene graphs. The method includes steps of S1, computing the aesthetic scores of optional locations and labeling the aesthetic scores; S2, designating path candidate regions according to start points and destinations; S3, acquiring information of distances between road nodes in thepath candidate regions, acquiring all feasible paths between every two points of the start points and the destinations by the aid of depth-first search algorithms by means of computation and acquiringcandidate path sets; S4, computing comprehensive aesthetic scores of each feasible path in the candidate path sets according to the aesthetic scores of the feasible path and the length of the feasible path and taking one or a plurality of paths with the highest comprehensive aesthetic scores. The aesthetic scores of the optional locations contain location street scene picture sets. The start points and the destinations are determined by users. The method has the advantages that the shortcoming of time and labor consuming of the traditional methods can be overcome by the aid of the method; theaesthetic scores are combined with the traditional path planning, accordingly, the most beautiful paths which conform to requirements can be recommended for the users, and the method has a broad application prospect.

Description

technical field [0001] The invention belongs to the field of route navigation, and in particular relates to a most beautiful route navigation method and system based on aesthetic scoring of street view images. Background technique [0002] With the popularity of smart phones and other devices and the development of geographic information technology, people use maps for navigation more and more. However, common navigation systems usually choose the shortest feasible route between two places. However, with the improvement of people's living standards and the development of tourism, people are traveling more and more often. The improvement of people's cultural and artistic accomplishments also makes people not meet the traditional viewing needs, and the visual requirements for scenic spots and routes are also getting higher and higher. [0003] At present, most GPS map programs can get the shortest path between the starting point and the ending point. But the shortest path i...
